Definitions

  • the present invention relates to an air filter cartridge, especially for an intake air filter for an internal combustion engine.
  • the invention further relates to an air filter with such an air filter cartridge.
  • Air filters having a filter medium are used to remove particulates from the air for com- bustion engines. Since the lifetime of such a filter medium is limited, the filter medium is installed in an air filter cartridge that can be exchanged. In order to keep particulates from bypassing the filter cartridge, the filter cartridge has to be tightly sealed to a filter housing of the air filter. Up to now, simultaneous easy exchange and tight sealing is a challenge with respect to the aforementioned air filters.
  • WO 201 1 /045225 A1 discloses an air filter for a vehicle.
  • the air filter can be used to remove particulate material from a gas flow going into a combustion engine of the vehicle.
  • the air filter has a precleaner, a main filter cartridge and a safety filter cartridge.
  • the safety filter cartridge cannot be pivoted relative to a filter housing of the air filter.
  • EP 1 748 831 B1 also shows an air filter having a precleaner, a main filter cartridge and a safety filter cartridge, which are installed in a housing of the air filter.
  • the safety filter cartridge according to EP 1 748 831 B1 has a projection that protrudes over a circumference of the safety filter cartridge. The projection can be inserted in a groove of the housing. Afterwards, the safety filter cartridge can be levered into its final position in the housing. The projection does not protrude in axial direction with respect to a passage axis of the safety filter cartridge.
  • EP 1 522 441 A1 discloses an air filter having a guidance for securing a filter cartridge at the bottom of the housing of the air filter.
  • the air filter provides a catch mechanism for securing the filter cartridge to the top of the housing.
  • EP 1 522 441 A1 does not disclose a protrusion, i.e. a tongue, that protrudes in axial direction with respect to its passage axis.
  • US 2008/021 6455 A1 shows an air filter with a housing. The housing has a slot. A filter cartridge can be inserted into the slot. The slot has a ramp that pushes the filter cartridge in a forward direction when inserted into the slot.
  • US 2008/021 6455 A1 does not disclose a sealing lip at the outer circumferential surface of the filter cartridge.
  • WO 98/12430 A1 discloses another air filter, especially for the intake air of an internal combustion engine.
  • a filter cartridge can be introduced in a housing of the air filter.
  • the housing has a groove at the connection of two parts of the housing.
  • WO 98/12430 A1 does not disclose a sealing lip at the outer circumferential surface of the filter cartridge.
  • WO 201 1 /045220 A2 shows an air filter comprising a filter cartridge with a frame running along the lateral surfaces of the filter cartridge.
  • the inlet side of the filter cartridge is detachable from the outlet side in a sealing manner, wherein the frame comprises a first and a second contact surface for clamping the filter cartridge.
  • the filter cartridge cannot be pivoted relative to a filter housing of the air filter.
  • EP 1 364 695 A1 discloses an air filter with a housing and a main filter.
  • the main filter is connected to the housing by means of a bayonet fitting.
  • the main filter as a whole can be screwed into the housing by using the bayonet fitting.
  • the main filter cannot be pivoted relative to a filter housing of the air filter.
  • an air filter cartridge and an air filter which possess an air filter cartridge that is both easy to install and sealing tightly in a filter housing of the air filter.
  • a tongue having a first end, which is connected to the frame and a free second end, said free second end being usable as a fulcrum to lever the air filter cartridge into a receiving portion of a filter housing of an air filter;
  • said free second end is axially displaced to the filter medium in a direction parallel to the passage axis.
  • the air filter cartridge provides excellent sealing properties due to its circumferential sealing lip at the outside of the frame.
  • a tongue i.e. a protrusion, arranges for effortless installation of the air filter cartridge inside a receiving portion of a filter housing of an air filter via providing a fix point that can be inserted in a mounting aid in the filter housing. Due to the fix point, i.e. a fulcrum, the air filter cartridge can easily be levered into the receiving portion. Since the second free end of the tongue, i.e. the aforementioned fix point, is displaced from the filter medium of the air filter cartridge in an axial direction parallel to the passage axis, the tongue does not negatively influence the sealing properties of the sealing lip. Would the tongue - in contrast thereto - be close to the sealing lip, then the air filter cartridge would tend to rest on the tongue rather than on the sealing lip, resulting in decreased sealing behavior of the sealing lip.
  • the frame is preferably injection-molded.
  • said frame has an overall oval shaped open cross section perpendicular to the passage axis of the air filter cartridge.
  • the frame has an oval shaped open cross section with straight side walls.
  • the frame preferably has an open cross section with two hemicyles, which are connected by straight side lines.
  • the air filter cartridge is easy to manufacture and saves precious space in the filter housing.
  • the aforementioned tongue has a flexible part, said flexible part having a round shape with respect to the longitudinal extent of the tongue.
  • the flexible part of the tongue has a round shape following the tongue from its first end - which is connected to the frame - to its free second end.
  • the flexible part of the tongue facilitates the installation of the air filter cartridge, since the flexible part is able to compensate for tolerances of the air filter cartridge and the filter housing. Furthermore, the flexible part can be pressed during installation of the air filter cartridge, resulting in a force fit of the air filter cartridge in the receiving portion. Finally, the rounded flexible part permits a smooth levering motion of the air filter cartridge into the receiving portion.
  • the flexible part may have a round shape transverse, especially perpendicular, to the longitudinal extent of the tongue.
  • the tongue can thus be placed snug in the round shaped filter housing.
  • said tongue may have an angled free second end. The angled free second end can then abut against an abutment means, especially in the form of a shoulder, of the filter housing.
  • Rationalized production can be achieved, when said tongue is molded in one piece with said frame or connected to said frame by a snap-fit connection.
  • the air filter cartridge is built metal-free.
  • the air filter cartridge can be incinerated completely after use.
  • the metal-free air filter cartridge is very environment-friendly.
  • the air filter cartridge is built in form of a safety filter cartridge.
  • Safety filter cartridges i.e. secondary filter cartridges, are deployed in order to protect an engine being connected to the air filter during exchange of a main filter of the air filter in a dirty environment. Such protection is especial- ly necessary, when a main filter is exchanged during running a combustion engine, which is connected to the air filter.
  • an air filter comprising an aforementioned air filter cartridge, said air filter further comprising a filter housing with a receiving portion, wherein said air filter cartridge is installable into the receiving portion, said filter housing comprising a mounting aid in the vicinity of the receiving portion, said mounting aid being built to receive the free second end of the tongue.
  • the filter housing is preferably injection molded.
  • the mounting aid can be built in form of a groove in the inside of the filter housing.
  • the mounting aid preferably comprises at least one protrusion that protrudes from an inner circumferential wall of the filter housing.
  • the mounting aid may comprise two protrusions that protrude from an inner circumferential wall of the filter housing, the protrusions each being configured as an L-shaped profile, with the upper part of the L being the side for levering the air filter cartridge into its predetermined seat, i.e. the receiving portion, and the lower part of the L providing a locating surface for preventing a rotation of the air filter cartridge around the passage axis.
  • the filter housing comprises abutment means for limiting the insertion depth of the air filter cartridge into the receiving section, said abutment means comprising a shoulder of the filter housing for abutment of the angled free second end of the tongue in the direction of the passage axis.
  • the air filter comprises a main filter and the air filter cartridge is a safety filter cartridge, the filter medium of the air filter cartridge having larger pores or pores of the same size with respect to said main filter.
  • the filter medium of the air filter cartridge thus provides for a coarse protection of an engine connected to the air filter.
  • the air filter comprises a precleaner, especially in the form of a cyclone arrangement, pre-separating particulates out of the airstream.
  • precleaner, main filter and safety filter cartridge may be ar- ranged in line. Furthermore, an outlet port of the air filter may be arranged in line in the direction of the passage axis.
  • Manufacturing of the air filter cartridge is significantly facilitated, when the air filter cartridge is built symmetrically to a middle plain cutting the passage axis. Furthermore it is preferred to build the filter housing symmetrically to a middle plain cutting the passage axis.
